CSC/ECE 517 Fall 2018/E1852 Unit Test for Participant Model

Expertiza

Expertiza is a web application where students can submit and peer-review learning objects (articles, code, web sites, etc). It is used in select courses at NC State and by professors at several other colleges and universities.

Steps for Implementation

Plan of Work

---

The task is to write unit test cases for testing the participant model file. The Rspec file participant_spec.rb existed with test cases for name and fullname methods. The procedure followed :-

1. Setting up the Expertiza environment

2. Understand the functionality of model file in participant.rb

3. Understand the linked data attributes being used, like assignment, topic, questionnaire

4. Writing testing conditions for different functions.

Test Cases

TASKS IDENTIFIED

Test team

A Participant can be a member of a Team. When team method is called on a Participant, it should return the Team it belongs to.

describe "#team" do
  it "returns the team id for the user" do
    expect(participant.team).to eq(nil)
  end   
end

Test responses

   def responses
    response_maps.map(&:response)
   end

A Participant has many ResponseMaps that map a connection between this participant as a reviewer and as a reviewee. Each ResponseMap has many Responses associated with it. When responses method is called on a Participant, it should return an array of responses associated to this Participant.

 describe '#responses' do
     it 'returns an array of responses of the participant' do
       expect(participant.responses).to eql([])
     end
end

The above test will test a participant with no corresponding mapping. Hence the result of the responses provided by the participant is a nil list

Test name

 def name(ip_address = nil)
    self.user.name(ip_address)
end

 describe "#name" do
    it "returns the name of the user" do
      expect(participant.name).to eq "Student"
    end
end

A Participant is a User. When name method is called on a Participant, it should return the name of this User. Link title

Test fullname

  def fullname(ip_address = nil)
    self.user.fullname(ip_address)
end

describe "#name" do
    it "returns the name of the user" do
      expect(participant.name).to eq "Student"
    end
end

A Participant is a User. When fullname method is called on a Participant, it should return the full name of this User.

Test handle

  def handle(ip_address = nil)
    User.anonymized_view?(ip_address) ? 'handle' : self[:handle]
end

Test delete

  def delete(force = nil)
    maps = ResponseMap.where('reviewee_id = ? or reviewer_id = ?', self.id, self.id)
    if force or (maps.blank? and self.team.nil?)
      force_delete(maps)
    else
      raise "Associations exist for this participant."
    end
end

Test force_delete

 
 def force_delete(maps)
    maps and maps.each(&:destroy)
    if self.team and self.team.teams_users.length == 1
      self.team.delete
    elsif self.team
      self.team.teams_users.each {|teams_user| teams_user.destroy if teams_user.user_id == self.id }
    end
    self.destroy
end

Test topic_name

 
 describe '#topic_name' do     
     context 'when the participant has an assignment without a topic' do
       it 'returns error message' do
         expect(participant.topic_name).to eql('<center>—</center>')
       end
end

Test able_to_review

 def able_to_review
   can_review
 end

When able_to_review method is called on a Participant, it should return true if it can review and false otherwise.

Test email

Test scores

When scores method is called on a Participant, it should return the total scores it received for a given number of questions.

Test get_permissions

Test get_authorization

Test sort_by_name

Participants are Users. When self.sort_by_name method is called on a Participant, it should sort a given set of participants based on their usernames.
